Introduction to the characteristics of flake graphite

1. As a basic raw material, flake graphite can be processed into ultrafine graphite powder, expanded graphite, nano graphite powder, high-purity graphite powder, etc.2. Flake graphite has good lubricity, high temperature resistance, conductivity, etc. Processed into solid graphite lubricant, widely used in mechanical lubrication.3. The quality of flake graphite depends on its carbon content. By purifying flake graphite, it can be processed into high carbon, medium carbon, and low carbon flake graphite. Each type of graphite has a different carbon content, and the higher the carbon content, the better its industrial use.Flake graphite has strong thermal shock resistance and good corrosion resistance, making it the main carbon material for carbon refractory materials. It has important factors affecting the corrosion resistance and high-temperature working strength of carbon refractory design materials such as magnesia carbon bricks. In the actual production process, carbon refractory ma

The Properties of Graphite and Its Application in Smelting

Graphite undergoes special forming methods to achieve its industrial application characteristics, namely special graphite. The three high graphite is commonly known as the three high graphite in the industry, but not all three high graphite is isostatic pressure graphite. In addition, there are materials such as molded and extruded graphite, which, due to their special structure, have high temperature resistance, conductivity, thermal conductivity, lubrication, chemical stability, and plasticity Characteristics such as thermal shock resistance.The application of graphite in the metallurgical industry is due to its high temperature resistance, thermal conductivity, stable chemical properties, and thermal shock resistance. In the metallurgical industry, graphite is mainly used as a refractory material. We are familiar with graphite crucibles, refractory bricks, and casting molds in the metallurgical industry. Graphite products are closely related to the smelting industry, and in the ste

Scales graphite has the cause of lubrication and the conditions of use

Scales graphite has many high -quality characteristics, especially good lubrication, so that it is widely used in many fields. Why is the scales graphite good lubricating, and under what conditions are better lubricating performance? Graphite manufacturer Xiaobian will analyze in detail for you:1, scales graphite is lubricated.The scales graphite played its good lubrication when there is water vapor and air. The presence of water and air enables the surface of the scale graphite to absorb water and gas molecules, which increases the distance between the sliding solution and weakens their binding force. On the one hand, the adhesion is also provided by the free keys on the edge of the base surface of the scales. Because water and gas molecules occupy these free keys, the adhesion force is reduced. This is why the scales are lubricated.2, scales graphite lubricating conditions.Scale graphic can only have good lubrication only in the case of water and air. For example, in a thin high alt

What is the purpose of expanding graphite

Adsorption agent of industrial oil.Expansion graphite is easily adsorbed, organic molecules and hydrophobic substances, which are used for water environmental protection. It has an irreplaceable effect of other substances. When it is used in a particle -shaped form to remove oil, according to the size of the oil area and the type of oil on the water surface, its dosage is 1 to LO% /RN, and the adsorption time can be ranging from 15rain to a few H.

Preparation process and application of ultrafine graphite powder

Ultrafine graphite powder is one type of graphite powder. The raw material of ultrafine graphite powder is natural flake graphite, which is crushed using an airflow grinder or ultrafine micro grinder. Ultrafine graphite powder with a particle size of 6-10 μ m. It's ultrafine graphite powder.The preparation process of ultrafine graphite powder is as follows: natural flake graphite and raw material coke enter the crushing chamber through a feeding injector with compressed air, and are distributed at the nozzles outside the crushing chamber to inject ultra-high speed airflow into the crushing chamber, causing the coke powder to collide and rub with each other at high speed to form micro powder. The airflow with micro powder is discharged into the grading chamber through the outlet pipe, separating the coarser particles and being crushed again through the return pipe, The remaining micro powder is collected in stages using a cyclone separator and a bag collector. Ultrafine graphite powder

The application of scales in the casting industry

1. Scales graphite is the main raw material for the casting industry.During the casting process, the scale graphite should be added to the casting, which helps the product to complete it faster and better, and improve the quality of the casting product. Therefore, the scale graphite for casting is the key raw material for the casting industry.2. How is graphite used to cast?Processing the cast -specific scales graphite into powder, and then add it to the outer surface of the casting and casting to make the casting easy to remove the mold. Casting dedicated scales graphite improves the surface quality of the casting, making the castings more abrasion and high temperature. This is the application of cast -specific scales graphite in casting and its abrasion resistance and high temperature resistance. There are many specifications for casting special sliced graphite powder. In different cast production areas, different thermal scale graphite should be used with different aims of casting.

The problem that graphite boat should pay attention to when maintenance is maintained

1. Prevention of strong corrosion of flame direct -injection engine graphite products side and bottom 砣;2. Use the entire process to turn the graphite boat once a week to improve the use period of graphite products;3. A proper interval should be kept in the middle of the graphite boat and the furnace wall, and graphite products should be put in the middle of the furnace;4. Pull out the coal ash and sticky conditions in the form of the form should be gently patted to prevent damaging graphite products;5. In the transportation conditions, it is necessary to hold it lightly, and it is strictly forbidden to fall;6. Strictly prevent the wet and cold, try to put it as much as possible or on the wooden shelf in the storage condition;7. The model specifications are the capacity of copper;8. Before using the dryer equipment or beside the furnace, it must be baked, and the temperature gradually rises to 500 ° C;9. The use of moderate combustion and additives will reduce the period of use.
